I'm having issues getting Arch Linux to boot. I'm trying to boot with GRUB2.04.
Starting version 243.78-2-arch
A password is required to access the cryptsys volume:
Enter passphrase for /dev/sda2:
ERROR: device 'UUID=7ac5c4f3-9769-442d-b166-4056f78500e' not found. Skipping fsck.
mount: /new_root: can't find UUID=7ac5c4f3-9769-442d-b166-4056f78500e.
You are now being dropped into an emergency shell.
sh: can't access tty: job control turned offI encrypted /root and /home with LUKS2 although https://wiki.archlinux.org/index.php/Dm … cryptsetup warns about GRUB2.04 not supporting LUKS2-Headers. According to the warning this should only be an issue if the /boot partition is encrypted. This is not the case in my setup.
According to https://bbs.archlinux.org/viewtopic.php?id=254056 it could also be a problem between the kernel and initramfs but I can't see any issues there in my grub.cfg (see below) either.

# MODULES
# The following modules are loaded before any boot hooks are
# run. Advanced users may wish to specify all system modules
# in this array. For instance:
# MODULES=(piix ide_disk reiserfs)
MODULES=(dm_mod)
# BINARIES
# This setting includes any additional binaries a given user may
# wish into the CPIO image. This is run last, so it may be used to
# override the actual binaries included by a given hook
# BINARIES are dependency parsed, so you may safely ignore libraries
BINARIES=()
# FILES
# This setting is similar to BINARIES above, however, files are added
# as-is and are not parsed in any way. This is useful for config files.
FILES=()
# HOOKS
# This is the most important setting in this file. The HOOKS control the
# modules and scripts added to the image, and what happens at boot time.
# Order is important, and it is recommended that you do not change the
# order in which HOOKS are added. Run 'mkinitcpio -H <hook name>' for
# help on a given hook.
# 'base' is _required_ unless you know precisely what you are doing.
# 'udev' is _required_ in order to automatically load modules
# 'filesystems' is _required_ unless you specify your fs modules in MODULES
# Examples:
## This setup specifies all modules in the MODULES setting above.
## No raid, lvm2, or encrypted root is needed.
# HOOKS=(base)
#
## This setup will autodetect all modules for your system and should
## work as a sane default
# HOOKS=(base udev autodetect block filesystems)
#
## This setup will generate a 'full' image which supports most systems.
## No autodetection is done.
# HOOKS=(base udev block filesystems)
#
## This setup assembles a pata mdadm array with an encrypted root FS.
## Note: See 'mkinitcpio -H mdadm' for more information on raid devices.
# HOOKS=(base udev block mdadm encrypt filesystems)
#
## This setup loads an lvm2 volume group on a usb device.
# HOOKS=(base udev block lvm2 filesystems)
#
## NOTE: If you have /usr on a separate partition, you MUST include the
# usr, fsck and shutdown hooks.
HOOKS=(base udev autodetect keyboard keymap consolefont modconf block encrypt lvm2 filesystems fsck)
# COMPRESSION
# Use this to compress the initramfs image. By default, gzip compression
# is used. Use 'cat' to create an uncompressed image.
#COMPRESSION="gzip"
#COMPRESSION="bzip2"
#COMPRESSION="lzma"
#COMPRESSION="xz"

Please append the contents of /etc/default/grub to the original post. I'm particularly interested in the "GRUB_CMDLINE_LINUX_DEFAULT=" line.
Is this a typo error?
The error message is complaining about 7ac5c4f3-9769-442d-b166-4056f78500e
while fstab and blkid shows 7ac5c4f3-9769-442d-b166-4056f785800e
Never argue with an idiot, they will drag you down to their level and then beat you with experience.

You were right! GRUB_CMDLINE_LINUX was set to ...root=UUID=7ac5c4f3-9769-442d-b166-4056f78500e with the missing 8. I
grub-mkconfig -o /boot/grub/grub.cfgagain and now everything seems to work fine.
I guess the incorrect value led to this in grub.cfg
linux /vmlinuz-linux root=/dev/mapper/VGsys-LVroot rw cryptdevice=UUID=4a8f7518-8279-40c5-a7ec-cbd8a4fbbd93:cryptsys root=UUID=7ac5c4f3-9769-442d-b166-4056f78500e loglevel=3 quietwith the same UUID set which caused the error.
Also since you mentioned "GRUB_CMDLINE_LINUX_DEFAULT" I probably should use this instead of "GRUB_CMDLINE_LINUX" although both work.
Thank you!
